CAP-SECURING MEANS FOR. GREASE-CUPS.

Specification of Letters Patent.

Patented Oct. 1, 1912.

Application filed November 25, 1911. Serial No. 662,519.

To all whom t't may concern;

Be it known-that I, NELs MORGAN, a citizen of the United .States of America, and'a resident of Funk, in the county of Phelps and State of Nebraska, have invented certain new and useful Improvements in Cap-' Securing Means for Grease-Cups, of which the following is a specification.

This invention relates to lubrication and particularly to grease cups and to means for securing thecaps of grease cups against accidental displacement. 4

An object of this invention is to provide novel means for yielding pressure on the caps of grease cups whereby movement of the cap with relation to the'grease cup is obviated so that the ar and vibration incident to the usemf machinery having such grease cups and covers or caps will not affect. the cap to the extent of displacing or. removing it, from the cup.

A still further object of this invention 'is to provide a-memberhaving yielding pressure on a cap of a grease cup, the said member beingreadily manipulated forthe purpose of releasing the pressure in order that opp is to be filled or for other purposes. a;

lVith the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of partsto be hereinafter more fully set forthand claimed.

In describing the invention in detail, reference will be had to the accompanying drawings, forming part of this specification wherein like characters denote corresponding parts in the several views, and in which 1 Figure 1 illustrates a view in elevation of a fragment of a lubricating pipe with the grease cup and means for holding the cap of the grease cup applied thereto; Fig. 2 illustrates a view similar to Fig. 1 taken at a point at right angles from-that which Fig. 1 is taken; and Fig. 3 illustrates a perspective view of the tension member.

In these drawings 4: denotes a housing to which thelubricating pipe 5 is connected,

the salid lubricating pipe having a-nipple 6 threaded internally to receive the stem 7 of the grease-cup 8, the said stem of the grease 1 cup having ashoulder 9 intermediate its length. The grease cup is preferably externally threaded as shown-at 10 for the purpose of receiving the threaded cap 11, the said threaded cap having a flange 12 at its top.

As a means for holding the cover of a grease cup, as heretofore explained, a ten sion member is provided comprising a me- .tall'ic strip shaped to form an eye or loop- 13 which fits over the stem 7 of the grease cup and is preferably interposed between the nipple 6 and the shoulder 9 wherein it is held loosely, but so as to prevent its displacement. The tension member has an arm 14:; with a coil 15 intermediate its length forming a spring which will afford movement of the arm, but it will at the same time exert suificient pressure or tension on the arm to hold the cover of the grease cup in the manner stated. As shown in the drawings, the outer or upper end of the arm 14 has-an end 16 standing at an angle to the arm, which end bears against the upper surface of the cover or cap of the grease cup,

preferably centrally thereof and the said" cap may be provided with a slight recess 17 in which the end of the arm rests or is seated so that the grease cup may be rotated by hand to overcome the tension of the spring while the end of the arm is resting in the recess, or if desired, the end of the arm may be removed from the seat and by lateral pressure, thereon, the said arm may be moved from over the top of the grease cup while the said cap is being manipulated.

I claim- A grease cup, comprising an externally threaded greasereceptacle, a recessed cap provided therefor, an externally shouldered stem; and a resilient arm; said arm having a loop adapted to engage said shoulder, a coil intermediate of its length, and a hook adapted to enter the recess in and exert pressure. onthe cap, thereby preventing accidental rotation of said cap.

In testimony whereof, I hereunto aflix my signature in the presence of two witnesses.

.NELS MORGAN.
